With the increasing degree of intellectualization, integration and network connection of automobiles, new technologies are constantly emerging, which bring more convenience to people's travel, but at the same time, they also need to bear the corresponding safety risks. According to car quality, according to data from the network as car intelligent degree unceasing enhancement, "av system failure", "car interconnected failure" and "driving safety assistant system malfunction" complaints present a stepwise increase in nearly three years, car failure rate increase year by year, let's have to the era of intelligent cars to re-examine security issues.

       At present, as various ECU (electronic control unit) modules and a large number of sensors begin to be widely used in automobile products, the electronic control system of vehicles is becoming more and more complex, and more and more intelligent functions can be realized, covering all aspects of people's travel. As ni weidou, the committee director of China's electric car in the third global smart car front summit (GIV 2020) puts it, "compared with the traditional sense of the car, smart car has expanded from a typical mechanical products for electric and electronic products, by a moving mechanical extension for the" super mobile intelligent terminal "and defined by the software of Internet products, high-tech electronic information products".

When it comes to the intelligence of automobiles, the first thing that comes to our mind is undoubtedly the hot self-driving technology in the past two years. However, the automatic driving is actually just a system embodiment of the phased development of the intelligence of automobiles, and all kinds of intelligent technologies involved behind it have already penetrated into our daily travel. In fact, automobile intelligence is a rather large system. According to the current development situation, it can be roughly divided into four components -- intelligent network connection, intelligent cockpit, intelligent driving and intelligent hardware. These four parts are not completely independent, but support each other.

The hidden danger of intelligent acceleration of automobile is becoming more and more prominent

        With the continuous development of automobile intelligence, the intelligent application of network information technology can not only satisfy People's Daily driving experience, but also enhance the driving pleasure in the driving process. Therefore, the "positioning" of the car has changed quietly, gradually transforming from the traditional functional model to the intelligent model, and correspondingly, a series of innovations have been made in the software and hardware of the car. The addition of a large number of ECU, various sensors, controllers, chips and other hardware, as well as network communication, cloud control platform, AI algorithm and other software, makes the car more and more "smart" at the same time, but also makes the internal system of the car more complex, inevitably brings some new problems and hidden dangers.

        According to car quality, according to data from the network for nearly three years to receive the failure problems related to the intelligent car complaints increased year by year, such as "av system failure" in the control panel black screen, caton and crash, "on-board interconnected failure" in the system cannot upgrade, vehicle function could not be opened, and "driving safety assistant system malfunction" in the active safety system, the problem such as lane departure warning system failure, complaints continue to increase. It is also reflected from the side that in the process of rapid intelligent development of vehicles, there are still many problems in software and hardware of vehicles. Some problems are related to driving experience, while others are closely related to the safety of drivers and passengers.

       Nowadays, large size of the control panel has become a mainstream industry, the function of its is not only a primary operation such as listening to music, navigation, with the emergence of intelligent, integrated machine system, the size of the control panel is more and more big, the function of bearing more and more, a lot of pure electric vehicles and even with a larger piece integrates all the function of the instrument panel. These include common functions such as driving mode selection, air conditioning control, seat heating/ventilation, and even mechanical controls such as seat, steering wheel, and rearview mirror adjustment, which are integrated into the central control screen. The advantage of high integration lies in convenient use and space saving, but it also has obvious disadvantages. Once the system software has problems, leading to the central control screen dead or black screen, most of the commonly used functions in the car cannot be used normally.

        A car owner reported to CHQ that his car suddenly encountered a black screen on the central control screen during normal use. Because the air conditioning control of the car was integrated on the central control screen and could not be turned on, the car owner had to open the window for ventilation in summer, which made him complain bitterly and seriously affected his driving experience. In addition to the failure of vehicle and engine system due to software problems alone, due to the mismatch between system chip model and software version, it is also common for the central control screen to get stuck and crash after system upgrade, which affects the normal use of part of the vehicle functions.

In addition, some hardware and software problems related to intelligent driving pose a threat to the safety of drivers and passengers.

       The vehicle quality network has received feedback from vehicle owners that when the vehicle is driving on the normal road and encounters obstacles, the vehicle will prompt the active braking system to start, but in fact the vehicle has not actively implemented any braking action. Fortunately, no casualties have been caused. This kind of problem is actually related to the failure of the vehicle's sensor or ECU. With the increasing degree of intelligence of the vehicle, the number of sensors and ECU mounted on the vehicle is also increasing, which is all over the braking, steering and other systems closely related to driving. Once the problem occurs, the consequences will be unimaginable.

The solution to the automobile safety problem in the intelligent age

Cars are safe and intelligent

        In many technology products, intelligence and safety are mutually beneficial, and to a certain extent, contradictory. The same is true for smart cars. The more intelligent the vehicle, the higher the safety factor of the vehicle, which is logically no problem. In fact, intelligence does improve vehicle safety, but it also brings more safety hazards, which can be seen in the frequent reports of intelligent car accidents. Therefore, in the development process of automobile intellectualization and network connection, safety problem is still the bottom line that cannot be ignored and cannot be crossed, and must be solved. In this regard, some experts in the industry believe that in the era of intelligence, the electronic system of the automobile is more and more complex, more and more faults, functional safety has become a necessary foundation for the development of high quality cars. This requires the whole automotive industry chain to integrate functional safety design, development and verification process methods into products to improve the level of automotive safety.

       In the era of intelligence, the industrial chain of intelligent vehicles is constantly stretched, and the coverage of the industrial chain of traditional fuel vehicles is extended to new fields such as informatization, network connectivity, big data and system software. Therefore, it is difficult to solve the hidden security problems of smart cars only by oems, which requires the cross-boundary cooperation of component manufacturers and high-tech enterprises.

        For component manufacturers, the functional safety of products should be fully considered in the early stage of intelligent product design and development, and the safety test of products should be strengthened in the full production cycle, and a complete set of verification procedures should be established. And for hosts at the top of the industry chain, more is to intelligent parts and vehicle matching degree, such as the compatibility between hardware and software for systematic testing and verification, and to develop effective car function of system security architecture, to ensure timely detect the potential security risks, and perform a reliable safety relief mechanism, in order to enhance the vehicle reliability and safety factor. In addition, CHQ also calls on relevant national departments to improve and add new national standards related to the safety of intelligent software and hardware functions of automobiles as soon as possible, so as to further supervise the production norms of relevant enterprises and guarantee the rapid development of intelligent automobiles.
